BACKGROUND

The present disclosure relates to attachment members and insulationpanels including the same. The insulation panels may be used on theexterior surface of a roofed and walled structure built for permanentuse, including a building, a house, etc.

In a building structure, such as a house, a frame is typically built outof wood, steel, block, or similar material. An exterior wall of plywoodor material of similar function is then placed upon the frame to providean exterior surface. A weatherproofing layer may cover the exteriorwall. An insulation layer can then be placed, and finally a cladding,paneling, sheathing, veneer, or siding is placed to provide the finalexterior view.

Vinyl siding is a popular substitute for wood paneling and aluminumsiding. It is easily cleaned, and it is resistant to deterioration. Itmay also be easily installed around windows and doors. Moreover, it maybe produced in a variety of shapes and colors by known extrusion andmolding processes at a relatively low cost per sheet or panel. Toenhance the thermal insulation of building structures, one or more layerof insulating material can be placed between the vinyl siding and theexterior wall of the building. For example, a layer of insulation can beattached to an exterior wall, and the vinyl siding then installed overthe insulating layer. In other insulated siding systems, an insulatedpanel is generally attached to a veneer, such as vinyl siding panel.

It would be desirable to produce additional insulated siding panelsystems or assemblies, as well as components thereof, that allow forsimple production, easy installation, and greater insulating properties.

The present disclosure relates to various embodiments of attachmentmembers which can be used to attach insulation to the wall of abuilding. The attachment member can be part of an insulation panel (alsoreferred to as a composite siding panel). The insulation panel includesthe attachment member and a foam insulation layer in which theattachment member is embedded. The insulation panel can also include aveneer panel or siding panel which is attached to the front of the foaminsulation layer.

Referring to the exemplary embodiment of FIG. 1, an attachment member100 generally has three parts. A connection portion or main portion 110of the attachment member has a forward edge 112 and a rear edge 114. Ahem portion or nailing hem 120 extends transversely from the rear edge114 of the main portion in an upper direction (indicated by arrow 102).The hem portion/nailing hem includes openings or receptacles (notvisible) through which fasteners (e.g. nails, staples, etc.) areinserted. A male connecting member or lower leg 130 extends transverselyfrom the main portion 110 in a lower direction (indicated by arrow 104).The upper direction 102 is opposite the lower direction 104. Describedin another way, the connection portion 110 joins the male connectingmember 130 and the hem portion 120 together. The male connectingmember/lower leg 130 has an upper or first end 132, and a lower orsecond end 134. The first end 132 of the lower leg is connected to theconnection portion/main portion 110.

In particular embodiments, the nailing hem 120 and the lower leg 130extend substantially perpendicularly from the main portion 110. Putanother way, the hem portion/nailing hem 120 and the male connectingmember/lower leg 130 are substantially parallel to each other.

In the exemplary embodiment shown in FIG. 1, the lower leg 130 isconnected to the main portion 110 along the forward edge 112. Theattachment member also includes a forward wall 140, which has a firstend 142 and a second end 144. The second end 144 of the forward wallconnects to the main portion 110 along the forward edge 112. The firstend 142 can also be referred to as the upper edge of the first wall. Theforward wall 140 extends in the upper direction 102 from the mainportion 110. As shown here, the lower leg 130, the forward wall 140, andthe nailing hem 120 may be substantially parallel to each other. Putanother way, the lower leg 130, the forward wall 140, and the nailinghem 120 extend substantially perpendicularly from the main portion 110.Also, the height 125 of the nailing hem is greater than the height 145of the forward wall.

FIG. 2 is a second exemplary embodiment of an attachment member. Here,the lower leg 130 connects to the main portion 110 in a central location116, rather than along the forward edge 112 as in FIG. 1. Put anotherway, the lower leg 130 connects to the main portion 110 at a pointbetween the forward edge 112 and the rear edge 114. In specificembodiments, the lower leg connects 130 to the main portion 110 at themidpoint 118 of the main portion. No forward wall is present here.

FIG. 3 is a third exemplary embodiment of an attachment member. Here,the nailing hem 120 has a base 122 that connects to the main portion110, and an apex 124 at the opposite end. The base 122 is thicker thanthe apex 124. The top of the base has an angle θ which is shown here asbeing 135°, and may generally be from about 120° to about 160°. Thisembodiment includes a forward wall 140. An optional lip 150 may extendtransversely from the first end or upper edge 142 of the forward wall.In addition, an anchor portion or flange 160 extends transversely fromthe male connecting member/lower leg 130. As shown here, the flange 160extends from the second end 134 of the lower leg. Generally the flange160 can extend away from the lower leg anywhere between the first end132 and the second end 134 of the lower leg, though usually closer tothe second end than the first end. In embodiments, the anchorportion/flange 160 is substantially parallel to the connectionportion/main portion 110. Here, the flange 160 extends for an equaldistance forward and backward of the lower leg 130. However, it iscontemplated that the flange 160 may extend in only one direction fromthe lower leg 130, or that the flange can extend for different distancesin the two directions from the lower leg.

FIG. 4 is a fourth exemplary embodiment of an attachment member. Here,the attachment member 100 includes the forward wall 140, lip 150, andflange 160 previously discussed in the other exemplary embodiments. Twospurs 170 extend from the base of the nailing hem. The spurs extendtransversely in the lower direction 104 and in the forward direction106. It should be noted that the apex 124 of the nailing hem here isrounded off in comparison to the embodiments of FIGS. 1-3.

Referring back to FIG. 3, the main portion 110 of the attachment membermay have a thickness 115 of from about 1.0 inches to about 2.0 inches.The nailing hem 120 of the attachment member may have a total height 125of from about 1.0 inches to about 4.5 inches. The base 122 of thenailing hem may have a height 123 of from about 0.5 inches to about 2.0inches. Generally, the bottom half of the nailing hem should beconsidered the base. The remainder of the nailing hem may be consideredthe apex 124. The forward wall 140 of the attachment member may have aheight 145 of from about 0.25 inches to about 3 inches, including fromabout 0.25 inches to about 1 inch. Again, it should be mentioned thatwhen a forward wall is present, the height 145 of the forward wall isless than the height 125 of the nailing hem. The lip 150 of theattachment member may have a width 155 of from about 0.01 inches toabout 0.1 inches. The lower leg 130 of the attachment member may have aheight 135 of from about 0.5 inches to about 2.0 inches. The flange 160of the attachment member may have a width 165 of from about 0.25 inchesto about 1.5 inches. It should be noted that the flange 160 is shorterthan the main portion 110 of the attachment member, i.e. width 165 isless than thickness 115.

FIG. 5 is a perspective view of the attachment member of FIG. 2, andillustrates additional aspects of the attachment member which apply toall embodiments described herein. Here, the openings/receptacles 126 inthe nailing hem 120 are visible. In addition, one or more apertures 136may be present in the lower leg 130 of the attachment member as well. Asexplained further herein, the lower leg can be embedded in a foaminsulating layer during formation of the foam layer, and these aperturescan further anchor the attachment member into the foam layer when foampasses through the apertures and solidifies. Such apertures in the lowerleg are not necessary, and may be absent. The upper surface 117 of themain portion is flat. The attachment member may have any desired length105, although it is contemplated that the length will be from about 3feet to about 6 feet, including about 4 feet.

The attachment members of the present disclosure are useful in forminginsulation panels or composite siding panels. The attachment members canbe inserted into a foam insulating layer, or can be embedded into thefoam insulating layer during the manufacture of the foam insulatinglayer. It is contemplated that this combination of attachment member andfoam insulating layer can be sold as an intermediate product to aproducer. A veneer panel or siding panel can also be attached to theinsulation panel/composite siding panel.

FIG. 6 is an exploded view of a first exemplary embodiment of aninsulation panel or composite siding panel. FIG. 7 shows the insulationpanel in an assembled form. FIG. 8 shows two insulation panels stackedupon each other to illustrate how their various parts interact.

The insulation panel 600 includes an attachment member 610, a foaminsulating layer 630, and a veneer panel 650. The attachment member 610shown here is the same as that of FIG. 1. A fastening means, illustratedhere as a nail 602, extends through the nailing hem 612 to attach theinsulation panel to, for example, an exterior wall of a building.

The foam insulating layer 630 includes a front face 632 which is spacedapart from a rear face 634. A first end edge 636 and a second end edge638 join the front face 632 and the rear face 634 at opposite ends ofthe foam insulating layer. (It should be noted that the first end edgeand the second end edges are also surfaces, but are referred to as edgesfrom this side view.) The front face 632, rear face 634, first end edge636, and second end edge 638 define a body 640 of the foam insulatinglayer. The front face 632 is angled with respect to the rear face 634.Put another way, the thickness 637 at the first end edge 636 is lessthan the thickness 639 at the second end edge 638.

When the attachment member 610 is inserted into the foam insulatinglayer, the foam insulating layer 630 may be considered to have a femaleconnecting member 642 extending into the body 640 along the first endedge 636, into which the male connecting member/lower leg 614 extends.Alternatively, the male connecting member/lower leg 614 may simply bedescribed as extending into the body 640 along the first end edge 636.The nailing hem 612 of the attachment member is substantially alignedwith the rear face 634 of the foam insulating layer. Described anotherway, in this embodiment, the main portion 618 of the attachment memberdoes not extend to the front face 632 of the foam insulating layer.

The veneer panel 650 has a front face 652, a rear face 654, a first endedge 656, and a second end edge 658. The veneer panel 650 is attached tothe front face 632 of the foam insulating layer by its rear face 654.The veneer panel shown in FIG. 6 also has a first wall 660 that extendstransversely rearward from the first end edge 656. This first wall 660is located at the height of the upper edge 617 of the forward wall 616of the attachment member, or is placed to cover the upper surface 645 ofthe tongue 644 of the foam insulating layer 630. The veneer panel 650also has a second wall 662 that extends transversely rearward from thesecond end edge 658. In this embodiment, the first wall 660 and secondwall 662 of the veneer panel are substantially parallel to each other.

Generally speaking, the attachment member 610 and the first end edge 636cooperate to be complementary in shape with the second end edge 638 ofthe foam insulating layer. This allows adjacent panels to engage eachother. In this exemplary embodiment, a tongue, protrusion, or firstjoining element 644 extends from the first end edge 636 of the foaminsulating layer along the front face 632. Similarly, a groove, rabbet,or second joining element 646 extends into the second end edge 638. Thetongue 644 is shaped to fit within the groove 646. The groove 646 issized to receive the tongue 644 of the foam insulating layer, theforward wall 616 of the attachment member, and the first wall 660 of theveneer panel. A recess 648 is present in the rear face 634 of the foaminsulating layer along the second end edge 638 and is shaped toaccommodate the nailing hem 612 of the attachment member. As a result,as seen in FIG. 8, adjacent panels can engage each other.

FIG. 9 is an exploded view of a second exemplary embodiment of aninsulation panel or composite siding panel. FIG. 10 shows the insulationpanel in an assembled form. FIG. 11 shows two insulation panels stackedupon each other to illustrate how their various parts interact.

The insulation panel 900 includes an attachment member 910, a foaminsulating layer 930, and a veneer panel 950. The attachment member 910shown here is the same as that of FIG. 2. A fastening means, illustratedhere as a nail 902, extends through the nailing hem 912 to attach theinsulation panel to, for example, an exterior wall of a building.

Again, the foam insulating layer 930 includes a front face 932 which isspaced apart from a rear face 934. A first end edge 936 and a second endedge 938 join the front face 932 and the rear face 934 at opposite endsof the foam insulating layer. The front face 932, rear face 934, firstend edge 936, and second end edge 938 define a body 940 of the foaminsulating layer. The front face 932 is angled with respect to the rearface 934. Put another way, the thickness 937 at the first end edge 936is less than the thickness 939 at the second end edge 938. Also,compared to the embodiment of FIG. 6, the first end edge 936 is flat(i.e. planar) from the front face 932 to the rear face 934. No joiningelement extends from the first end edge. The attachment member 910entirely covers the first end edge 936 of the foam insulating layer.

The foam insulating layer 930 may be considered to have a channel orfemale connecting member 942 extending into the body 940 along the firstend edge 936, into which the male connecting member/lower leg 914extends. Alternatively, the male connecting member/lower leg 914 maysimply be described as extending into the body 940 along the first endedge 936. The nailing hem 912 of the attachment member is substantiallyaligned with the rear face 934 of the foam insulating layer.

The veneer panel 950 has a front face 952, a rear face 954, a first endedge 956, and a second end edge 958. The veneer panel 950 is attached tothe front face 932 of the foam insulating layer by its rear face 954.Here, the first end edge 956 of the veneer panel is adjacent the firstend edge 936 of the foam insulating layer. A first wall 960 of theveneer panel extends transversely upward from the first end edge 956 ofthe veneer panel beyond the first end edge 936 of the foam insulatinglayer. However, the upper edge 961 of the first wall 960 of the veneerpanel is below the apex 913 of the nailing hem 912. Compared to theembodiment of FIGS. 6-8, the first wall 960 could be considered a roughequivalent of the forward wall 516 of the attachment member. In specificembodiments, the first wall 960 of the veneer panel is substantiallyparallel to the nailing hem 912 of the attachment member, or in otherwords is substantially perpendicular to the main portion 918 of theattachment member.

The second end edge 958 of the veneer panel extends beyond the secondend edge 938 of the foam insulating layer. The veneer panel 950 also hasa second wall 962 that extends transversely rearward from the second endedge 958. A rear segment 949 extends from the second end edge 938 of thefoam insulating layer along the rear face 934.

Again, the attachment member 910 and the first end edge 936 cooperate tobe complementary in shape with the second end edge 938 of the foaminsulating layer, so that adjacent panels can engage each other. As seenin FIG. 10, the rear segment 949 is complementary to a channel 970formed by the first wall 960 of the veneer panel and the attachmentmember 910. The second wall 962 has a width 964 such that a pocket 972is formed between the rear segment 949 of the foam insulating layer, thesecond end edge 938 of the foam insulating layer, and the second wall962 of the veneer panel. The first wall 960 of the veneer panel fitsbetween the second wall 962 and the rear segment 949. A recess 948 ispresent in the rear face 934 of the foam insulating layer along thesecond end edge 938 and is sized to accommodate the nailing hem 912 ofthe attachment member. As a result, as seen in FIG. 11, adjacent panelscan engage each other.

FIG. 12 is an exploded view of a third exemplary embodiment of aninsulation panel or composite siding panel. FIG. 13 shows the insulationpanel in an assembled form. FIG. 14 shows two insulation panels stackedupon each other to illustrate how their various parts interact.

The insulation panel 1200 includes an attachment member 1210, a foaminsulating layer 1230, and a veneer panel 1250. The attachment member1210 shown here is similar to the one depicted in FIG. 3, and does nothave the lip. Rather, the attachment member is made up of the mainportion 1218, nailing hem 1212, lower leg 1214, forward wall 1216, andthe flange 1220 extending transversely from the lower end of lower leg1214. The base 1223 of the nailing hem 1212 is thicker than the apex1221 of the nailing hem. A fastening means is illustrated here as a nail1202 extending through the nailing hem 1212. The flange is useful inimproving wind load performance of the overall panel, as well asincreasing pull-out resistance (i.e. separation of the attachment memberfrom the foam insulating layer).

Again, the foam insulating layer 1230 includes a front face 1232 whichis spaced apart from a rear face 1234. A first end edge 1236 and asecond end edge 1238 join the front face 1232 and the rear face 1234 atopposite ends of the foam insulating layer. The front face 1232, rearface 1234, first end edge 1236, and second end edge 1238 define a body1240 of the foam insulating layer. The front face 1232 is angled withrespect to the rear face 1234. Put another way, the thickness 1237 atthe first end edge 1236 is less than the thickness 1239 at the secondend edge 1238. Here, like the embodiment of FIG. 9, the first end edge1236 is planar (i.e. flat) from the front face 1232 to the rear face1234. No joining element extends from the first end edge. The attachmentmember 1210 entirely covers the first end edge 1236 of the foaminsulating layer. A groove 1242 is located in the second end edge 1238of the foam insulating layer. The groove divides the body along thesecond end edge 1238 into a front ridge 1244 and a rear ridge 1246.

In this embodiment, the male connecting member/lower leg 1214 and theflange 1220 are embedded in the body 1240 along the first end edge 1236.The nailing hem 1212 of the attachment member is substantially alignedwith the rear face 1234 of the foam insulating layer.

The veneer panel 1250 has a front face 1252, a rear face 1254, a firstend edge 1256, and a second end edge 1258. The veneer panel 1250 isattached to the front face 1232 of the foam insulating layer by its rearface 1254. The first end edge 1256 of the veneer panel is adjacent thefirst end edge 1236 of the foam insulating layer. As depicted here, themain portion 1218 of the attachment member extends beyond the front face1232 of the foam insulating layer, such that the first end edge 1256 ofthe veneer panel also abuts the lower surface 1224 of the main portion1218.

However, it is also possible that a first wall of the veneer panel couldextend transversely upward from the first end edge 1256 of the veneerpanel beyond the first end edge 1236 of the foam insulating layer,similar to the veneer panel depicted in FIG. 9. That first wall would beadjacent to the forward wall 1216 of the attachment member and the upperedge of that first wall would end below the apex 1221 of the nailing hem1212. It is also possible that the attachment member would include alip, with the lip capping the first wall extending from the veneerpanel.

Returning to FIG. 12, the veneer panel includes a channel 1280 thatextends transversely rearward from the second end edge 1258 of theveneer panel. The channel 1280 is made from a lower wall 1282 and a rearwall 1284 that extends upwards from the end of the lower wall. The frontridge 1244 on the second end edge of the foam insulating panel entersthe channel 1280. The rear wall 1284 enters the groove 1242.

Again, the attachment member 1210 and the first end edge 1236 cooperateto be complementary in shape with the second end edge 1238 of the foaminsulating layer, so that adjacent panels can engage each other. As seenin FIG. 14, the rear ridge 1246 fits into the attachment member 1210.The groove 1242 on the second end edge of the foam insulating layer iscomplementary to the forward wall 1216 of the attachment member, so thatthe forward wall 1216 enters the groove 1242. A recess 1248 is presentin the rear face 1234 of the foam insulating layer along the second endedge 1238 and is sized to accommodate the nailing hem 1212 of theattachment member. As a result, adjacent panels can engage each other.

FIG. 15 is an exploded view of a fourth exemplary embodiment of aninsulation panel or composite siding panel. FIG. 16 shows the insulationpanel in an assembled form. FIG. 17 shows two insulation panels stackedupon each other to illustrate how their various parts interact.

The insulation panel 1500 includes an attachment member 1510, a foaminsulating layer 1530, and a veneer panel 1550. The attachment member1510 shown here is similar to the one depicted in FIG. 3, again withoutthe lip. The attachment member is made up of the main portion 1518,nailing hem 1512, lower leg 1514, forward wall 1516, and the flange 1520extending transversely from the lower end of lower leg 1514. The base1523 of the nailing hem 1512 is thicker than the apex 1521 of thenailing hem. A fastening means is illustrated here as a nail 1502extending through the nailing hem 1512.

Again, the foam insulating layer 1530 includes a front face 1532 whichis spaced apart from a rear face 1534. A first end edge 1536 and asecond end edge 1538 join the front face 1532 and the rear face 1534 atopposite ends of the foam insulating layer. The front face 1532, rearface 1534, first end edge 1536, and second end edge 1538 define a body1540 of the foam insulating layer.

Here, like the embodiments of FIG. 9 and FIG. 12, the first end edge1536 is planar (i.e. flat) from the front face 1532 to the rear face1534. No joining element extends from the first end edge. The attachmentmember 1510 entirely covers the first end edge 1536 of the foaminsulating layer. However, unlike those two embodiments, here, the frontface 1532 is substantially parallel to the rear face 1534. Put anotherway, the thickness 1537 of the foam insulating layer between the frontface 1532 and the rear face 1534 is generally constant from the firstend edge 1536 to the second end edge 1538. The exceptions to thisstatement relate to the presence of a groove 1542 in the front face 1532of the foam insulating layer along the second end edge, and the presenceof a recess 1548 in the rear face of the foam insulating layer along thesecond end edge. The groove 1542 could also be considered a frontrecess, in comparison to the recess 1548 in the rear face. The first endedge 1536 is substantially perpendicular to the front face 1532 and therear face 1534.

Again, the male connecting member/lower leg 1514 and the flange 1520 areembedded in the body 1540 along the first end edge 1536. The nailing hem1512 of the attachment member is substantially aligned with the rearface 1534 of the foam insulating layer. The forward wall 1516 of theattachment member is substantially parallel to the front face 1532 ofthe foam insulating layer.

The veneer panel 1550 has a front face 1552, a rear face 1554, a firstend edge 1556, and a second end edge 1558. The veneer panel 1550 isattached to the front face 1532 of the foam insulating layer by its rearface 1554. The first end edge 1556 of the veneer panel is adjacent thefirst end edge 1536 of the foam insulating layer. As depicted here, themain portion 1518 of the attachment member extends beyond the front face1532 of the foam insulating layer, such that the first end edge 1556 ofthe veneer panel also abuts the lower surface 1524 of the main portion1518. The second end edge 1558 of the veneer panel abuts the top of thegroove 1542 in the front face.

Generally speaking, the veneer panel 1550 here is flat. Describedanother way, the front face 1552 is substantially parallel to the rearface 1554. Put in other words, the thickness 1553 of the foam insulatinglayer between the front face 1552 and the rear face 1554 is generallyconstant from the first end edge 1556 to the second end edge 1558.

Again, it is also possible that a first wall of the veneer panel couldextend transversely upward from the first end edge 1556 of the veneerpanel beyond the first end edge 1536 of the foam insulating layer,similar to the veneer panel depicted in FIG. 9. That first wall would beadjacent to the forward wall 1516 of the attachment member and the upperedge of that first wall would end below the apex 1521 of the nailing hem1512. It is also possible that the attachment member would include alip, with the lip capping the first wall extending from the veneerpanel.

Again, the attachment member 1510 and the first end edge 1536 cooperateto be complementary in shape with the second end edge 1538 of the foaminsulating layer, so that adjacent panels can engage each other. As seenin FIG. 17, the second end edge 1538 of the foam insulating layer fitsinto the attachment member 1510. The forward wall 1516 of the attachmentmember enters the groove 1542 in the front face of the foam insulatinglayer. The recess 1548 in the rear face 1534 of the foam insulatinglayer is sized to accommodate the nailing hem 1512 of the attachmentmember. As a result, adjacent panels can engage each other.

FIG. 18 is view of an assembled fifth exemplary embodiment of aninsulation panel or composite siding panel. FIG. 19 shows two insulationpanels stacked upon each other to illustrate how their various partsinteract.

This fourth embodiment of an insulation panel 1800 is very similar tothe embodiment shown in FIG. 15. One large difference is that thisinsulation panel is formed only from an attachment member 1810 and afoam insulating layer 1830. No veneer panel is present. The attachmentmember 1810 shown here is the one depicted in FIG. 4. The attachmentmember is made up of the main portion 1818, nailing hem 1812, lower leg1814, forward wall 1816, the flange 1820 extending transversely from thelower end of lower leg 1814, and the lip 1826 extending transverselyfrom the upper end of the forward wall 1816. The base 1823 of thenailing hem 1812 includes spurs 1828. A fastening means is illustratedhere as a nail 1802 extending through the nailing hem 1812.

Again, the foam insulating layer 1830 includes a front face 1832 whichis spaced apart from a rear face 1834. A first end edge 1836 and asecond end edge 1838 join the front face 1832 and the rear face 1834 atopposite ends of the foam insulating layer. The front face 1832, rearface 1834, first end edge 1836, and second end edge 1838 define a body1840 of the foam insulating layer.

The first end edge 1836 is planar (i.e. flat) from the front face 1832to the rear face 1834. No joining element extends from the first endedge. The attachment member 1810 entirely covers the first end edge 1836of the foam insulating layer. The front face 1832 is substantiallyparallel to the rear face 1834. Put another way, the thickness of thefoam insulating layer between the front face 1832 and the rear face 1834is generally constant from the first end edge 1836 to the second endedge 1838. The exceptions to this statement relate to the presence of agroove 1842 in the front face 1832 of the foam insulating layer alongthe second end edge, and the presence of a recess 1848 in the rear faceof the foam insulating layer along the second end edge. The groove 1842could also be considered a front recess, in comparison to the recess1848 in the rear face. The first end edge 1836 is substantiallyperpendicular to the front face 1832 and the rear face 1834.

Again, the male connecting member/lower leg 1814 and the flange 1820 areembedded in the body 1840 along the first end edge 1836. The nailing hem1812 of the attachment member is substantially aligned with the rearface 1834 of the foam insulating layer. The forward wall 1816 of theattachment member is substantially parallel to the front face 1832 ofthe foam insulating layer.

The attachment member 1810 and the first end edge 1836 cooperate to becomplementary in shape with the second end edge 1838 of the foaminsulating layer, so that adjacent panels can engage each other. As seenin FIG. 19, the second end edge 1838 of the foam insulating layer fitsinto the attachment member 1810. The forward wall 1816 of the attachmentmember enters the groove 1842 in the front face of the foam insulatinglayer. The recess 1848 in the rear face 1834 of the foam insulatinglayer is sized to accommodate the nailing hem 1812 of the attachmentmember. As a result, adjacent panels can engage each other. The spurs1828 help to prevent separation between the adjacent panels.

FIG. 20 is an exploded side view of a sixth exemplary embodiment of aninsulation panel or composite siding panel. FIG. 21 is a side view ofthe insulation panel. FIG. 22 shows two insulation panels stacked uponeach other to illustrate how their various parts interact.

The insulation panel 2000 includes an attachment member 2010, a foaminsulating layer 2030, and a veneer panel 2050. The attachment member2010 shown here is similar to the one depicted in FIG. 4. The attachmentmember is made up of the main portion 2018, nailing hem 2012, lower leg2014, forward wall 2016, the lip 2026 extending from an upper edge ofthe forward wall 2016, and the flange 2020 extending transversely fromthe lower end of lower leg 2014. The base 2023 of the nailing hem 2012is depicted with only one spur 2028. It should be noted that this spurdiffers from FIG. 4 in that the spur extends perpendicularly from thebase in a forward direction 2006, and does not extend in the lowerdirection, and there is only one spur. However, multiple spurs could beused, and if desired the spur could also extend in the lower direction.A fastening means is illustrated here as a nail 2002 extending throughthe nailing hem 2012. The flange is useful in improving wind loadperformance of the overall panel, as well as increasing pull-outresistance (i.e. separation of the attachment member from the foaminsulating layer).

Again, the foam insulating layer 2030 includes a front face 2032 whichis spaced apart from a rear face 2034. A first end edge 2036 and asecond end edge 2038 join the front face 2032 and the rear face 2034 atopposite ends of the foam insulating layer. The front face 2032, rearface 2034, first end edge 2036, and second end edge 2038 define a body2040 of the foam insulating layer. The front face 2032 is angled withrespect to the rear face 2034. Put another way, the thickness 2037 atthe first end edge 2036 is less than the thickness 2039 at the secondend edge 2038. The first end edge 2036 is planar (i.e. flat) from thefront face 2032 to the rear face 2034. No joining element extends fromthe first end edge. The attachment member 2010 entirely covers the firstend edge 2036 of the foam insulating layer. A groove 2042 is located inthe second end edge 2038 of the foam insulating layer. The groovedivides the body along the second end edge 2038 into a front ridge 2044and a rear ridge 2046.

In this embodiment, the lower leg 2014 and the flange 2020 of theattachment member are embedded in the body 2040 of the foam insulatinglayer along the first end edge 2036. The nailing hem 2012 of theattachment member is substantially aligned with the rear face 2034 ofthe foam insulating layer.

The veneer panel 2050 has a front face 2052, a rear face 2054, a firstend edge 2056, and a second end edge 2058. The veneer panel 2050 isattached to the front face 2032 of the foam insulating layer by its rearface 2054. The first end edge 2056 of the veneer panel extendstransversely upwards beyond the first end edge 2036 of the foaminsulating layer, so that the first end edge 2056 is adjacent the upperedge 2017 of the forward wall 2016. The lip 2026 caps the veneer panel2050. In this regard, it should be noted that the forward wall 2016 ofthe attachment member depicted in FIG. 20 is slightly different from theforward wall 140 of the attachment member depicted in FIG. 4. In FIG. 4,the forward wall 140 is perpendicular to the main portion 110. Here inFIG. 20, the forward wall 2016 is angled, so that the forward wall 2016is parallel to the front face 2032 of the foam insulating layer. Thus,the front face 2052 of the veneer panel can be flat.

The veneer panel 2050 includes a lower wall 2082 that extendstransversely rearward from the second end edge 2058 of the veneer panel.The lower wall 2082 runs adjacent the front ridge 2044 on the second endedge of the foam insulating layer, and ends at the groove 2042. Ifdesired, the lower wall could be part of a channel like that depicted inFIG. 12.

Again, the attachment member 2010 and the first end edge 2036 cooperateto be complementary in shape with the second end edge 2038 of the foaminsulating layer, so that adjacent panels can engage each other. As seenin FIG. 22, the rear ridge 2046 fits into the attachment member 2010.The groove 2042 on the second end edge of the foam insulating layer iscomplementary to the forward wall 2016 of the attachment member, so thatthe forward wall 2016 and a portion of the veneer panel 2050 enter thegroove 2042. A recess 2048 is present in the rear face 2034 of the foaminsulating layer along the second end edge 2038 and is sized toaccommodate the nailing hem 2012 of the attachment member. As a result,adjacent panels can engage each other.

More generally, the insulation panel 2000 could be described as beingformed from an attachment member 2010, a foam insulating layer 2030, anda veneer panel 2050. The foam insulating layer has a front face 2032, arear face 2034, a first end edge 2036, and a second end edge 2038 thatdefine a body 2040 of the foam insulating layer. The attachment member2010 comprises a main portion 2018 resting upon the first end edge 2036of the foam insulating layer, a forward wall 2016 extending transverselyfrom a forward edge of the main portion 2018 away from the foaminsulating layer 2030, and a lower leg 2014 extending transversely fromthe main portion into the body 2040 of the foam insulating layer. Theveneer panel 2050 is attached to the front face 2032 of the foaminsulating layer, a first end edge 2056 of the veneer panel beingadjacent to an upper edge 2017 of the forward wall 2016 of theattachment member.

FIG. 23 is a side view of a variation on the attachment member which canapply to all embodiments described herein, including at least FIGS. 1-4.FIG. 24 is a perspective view. The attachment member 2300 has a mainportion 2310, a hem portion or nailing hem 2320, and a lower leg 2330.The main portion 2310 of the attachment member has a forward edge 2312and a rear edge 2314.

The hem portion 2320 extends transversely from the rear edge 2314 of themain portion in an upper direction (indicated by arrow 2302). Thenailing hem 2320 has a base 2322 that connects to the main portion 2310,and an apex 2324 at the opposite end. The nailing hem also includesopenings or receptacles 2326 (visible in FIG. 24) for fasteners. Onespur 2370 extends from the base 2322 of the nailing hem. Again, thesespurs extend only in the forward direction 2306, or put another wayparallel to the main portion 2310, and do not extend in the lowerdirection 2304. Again, more than one spur may be present. The apex 2324of the nailing hem here is rounded off.

The embodiment illustrated in FIG. 23 and FIG. 24 also includes aforward wall 2340, which has a first end 2342 and a second end 2344. Itshould be noted again that the forward wall is optional (as seen in FIG.2). The second end 2344 of the forward wall connects to the main portion2310 along the forward edge 2312. The first end 2342 can also bereferred to as the upper edge of the first wall. The forward wall 2340extends in the upper direction 2302 from the main portion 2310. As shownhere, the lower leg 2330, the forward wall 2340, and the nailing hem2320 may be substantially parallel to each other. Put another way, thelower leg 2330, the forward wall 2340, and the nailing hem 2320 extendsubstantially perpendicularly from the main portion 2310. Also, theheight 2325 of the nailing hem is greater than the height 2345 of theforward wall. An optional lip 2350 may extend transversely from thefirst end or upper edge 2342 of the forward wall in the forwarddirection 2306.

The lower leg 2330 extends transversely from the main portion 2310 in alower direction (indicated by arrow 2304). The upper direction 2302 isopposite the lower direction 2304. Described in another way, theconnection portion 2310 joins the lower leg 2330 and the hem portion2320 together. The lower leg 2330 has an upper or first end 2332, and alower or second end 2334. The first end 2332 of the lower leg isconnected to the main portion 2310. Here, the lower leg 2330 connects tothe main portion 2310 in a central location 2316. Put another way, thelower leg 2330 connects to the main portion 2310 at a point between theforward edge 2312 and the rear edge 2314, such as the midpoint 2318 ofthe main portion.

In particular embodiments, the nailing hem 2320 and the lower leg 2330extend substantially perpendicularly from the main portion 2310. Putanother way, the hem portion 2320 and the lower leg 2330 aresubstantially parallel to each other.

The main variation illustrated here is in the shape of the lower leg2330 and the flange(s) 2360 extending from the lower leg. As explainedfurther below, one method of joining the attachment member to a foaminsulating layer involves “stabbing” the foam insulating layer with thelower leg of the attachment member to fasten the two componentstogether. The flange increases the pull-out resistance of the attachmentmember. However, the shape of the lower leg and the flange can bothincrease the ease of insertion and increase the pull-out resistance.

In the variation of FIG. 23 and FIG. 24, one or more flanges 2360 arepresent extending transversely from the lower leg 2330. Together, thelower leg 2330 and the flange(s) 2360 have the shape of an invertedtree. Put another way, the lower leg has an arboriform or dendriformshape. The lower leg 2330 can be thought of here as the “trunk”. Theflanges 2360 are the “branches” and have a pointed shape.

Each flange includes a stop surface 2402 and an angled surface 2404. Thestop surface increases the difficulty of pulling the attachment memberout of the foam insulating layer after insertion. The stop surface 2402extends transversely from the lower leg 2330. The angled surface 2404 isangled with respect to the stop surface 2402, shown here as angle ω.Angle ω is acute and generally has a value of from about 15° to about75°. The angled surface 2404 angles away from the main portion 2310toward the lower end 2334 of the lower leg 2330. The angled surfaceeases the insertion of the attachment member into the foam insulatinglayer. The stop surface 2402 of each flange is closer to the mainportion 2310 than the angled surface 2404. The stop surface is usuallysubstantially parallel to the lower surface 2319 of the main portion2310. However, the stop surface can also be angled with respect to thelower surface 2319 of the main portion as well.

At least one flange is present, but generally any number of flanges maybe present. In FIG. 23, there are three flanges 2360, numbered here astertiary flange 2382, secondary flange 2384, and primary flange 2386.The primary flange is located at the lower end 2334 of the lower leg2330. The other flanges are spaced along the length of the lower leg.Put another way, the primary flange is further from the main portionthan the other flanges. The lower end 2334 itself is pointed. Dottedlines are present in FIG. 23 to show the difference between the lowerleg 2330 and the flanges 2360.

As seen in the embodiment of FIG. 23, the stop surface 2402 has a length2365. In FIG. 23, the stop surfaces of all three flanges 2382, 2384,2386 have the same length.

FIG. 24 is a perspective view of the attachment member of FIG. 23. Thereceptacles 2326 in the nailing hem 2320 are visible. The upper surface2317 of the main portion is flat. The stop surfaces 2402 on each flange2360 are also flat. The attachment member may have any desired length2305.

FIG. 25 depicts a different embodiment in which the stop surfaces ofdifferent flanges have different lengths. In FIG. 25, there are threeflanges numbered here as tertiary flange 2410, secondary flange 2420,and primary flange 2430. Tertiary flange 2410 has a stop surface 2412and an angled surface 2414. The tertiary stop surface 2412 has atertiary length 2413. Secondary flange 2420 has a stop surface 2422 andan angled surface 2424. The secondary stop surface 2422 has a secondarylength 2423. Primary flange 2430 has a stop surface 2432 and an angledsurface 2434. The primary stop surface 2432 has a primary length 2433.The lengths 2413, 2423, 2433 of the stop surfaces are measured from thelower leg 2330 parallel to the lower surface 2319 of the main portion2310.

Tertiary length 2413 is greater than both secondary length 2423 andprimary length 2433. Secondary length 2423 is less than tertiary length2413 and greater than primary length 2433. Primary length 2433 is lessthan both tertiary length 2413 and secondary length 2423. In otherwords, the tertiary flange is longer than the secondary flange, which islonger than the primary flange. Generally, a flange which is relativelycloser to the main portion 2310 should have a stop surface whose lengthis greater than that of a flange which is relatively further from themain portion 2310.

Referring to FIG. 18 though applying to all embodiments, the foaminsulating layer generally has a thickness of from about 1.0 inches toabout 4.0 inches, with the thickness varying if the foam insulatinglayer is contoured. This thickness may be measured along the first endedge (reference numeral 1837) or along the second end edge (referencenumeral 1839). The foam insulating layer may have a height 1805 of fromabout 8 inches to about 48 inches, as desired. In some embodiments, theheight 1805 is from about 12 inches to about 24 inches.

The attachment member is typically made from a polymeric material knownin the art. The attachment member is typically made by injectionprocesses where the polymeric material is melted and injected into a diemold. The polymeric material is then cooled and removed from the diemold.

The veneer panel and the attachment member can be attached to theinsulating layer in a variety of ways including, but not limited to,adhesive, chemical bonding, interlocking complementary surfaces, and/orfasteners. Typically, however, adhesives are used. The adhesive may beused over the entire surface of the veneer panel or the attachmentmember, or used in discrete locations. Suitable adhesives may include,but are not limited to, UV curable adhesives and hot melt adhesives,such as polyamines and urethanes, glue, thermosetting or thermoplasticadhesives, pressure sensitive adhesives or solvent-based adhesives.

At least three ways of attaching the attachment member to the foaminsulating layer are contemplated. First, the foam insulating layer ismade with the first end edge containing a channel, and the lower leg ofthe attachment member is slid into the channel from the side. Second,the foam insulating layer is made without a channel in the first endedge, and the attachment member may be pressed or stabbed into the foaminsulating layer and adhered in place. Third, the attachment member maybe embedded in the foam insulating layer during the shape moldingprocess, as described further below. The attachment member may belocated to allow the insulation panel to be fastened to the wall withoutcreating penetrations in the veneer panel or the foam insulating layer.

The foam insulating layer may be shape molded. Such molding operationswill generally impart the desired contours and/or design to the foaminsulating layer. Typically, beads and/or pellets of a polymericprecursor material, such as pre-expanded polystyrene, are placed in asuitably configured die mold, then reacted in the presence of water andheat (i.e. steam) to expand during the reaction process. The polymericprecursor material expands and presses against the die surface to formcompressed, elongated closed calls that form a characteristic toughsmooth skin. The shape molded process produces a panel that isessentially straight and/or free of camber. It is contemplated that theattachment member can be placed in the die mold prior to the expansionof the polymeric precursor material. This embeds the attachment memberinto the foam insulating layer as the polymeric material is expanded,such that no secondary fasteners are needed.

The foam insulating layer provides structural integrity to the insulatedsiding panel. For example, the foam insulating layer is the platform towhich the veneer panel and the attachment member are connected. The foaminsulating layer may be shaped to provide the desired profile for theoverall insulated siding panel. For example, the shape of the foaminsulating layer may be obtained by either suitable shaping of the diemold, or by computer numerical control (CNC) cutting. The grooves and/orfemale attachment members may also be milled or wire-cut.

The foam insulating layer is generally made from a cellular foamproduct, i.e. a plastic or polymeric material with numerous cells oftrapped air distributed throughout its mass. For example, expandedpolystyrene (EPS) is a cellular foam plastic made from beads ofpolystyrene that are first pre-expanded and allowed to rest for asuitable interval, then molded in closed steam-heated shaped molds toproduce closed-cell molded foams. The size and density of the closedcells can be controlled and may vary depending upon the application.Suitable materials for the foam insulating layer can include extrudedpolystyrene (XPS), expanded polystyrene (EPS), polyurethane,polyisocyanurate, polyethylene, polypropylene, or combinations thereof.In some embodiments, the foam insulating layer is made from a rigid foammaterial.

The foam insulating layer can be of any density desired, or be tuned toprovide different densities depending on the location. For example, itmay be desirable to have higher densities near the edges of the panel,and lower densities near the center (where the veneer panel covers thefoam insulating layer). In particular embodiments, the foam insulatinglayer has a higher density along the first end edge or upper edge thanin the center of the foam insulation layer (i.e. the middle region ofthe foam insulation layer between the first end edge and the second endedge). Similarly, the foam insulation layer may also have a higherdensity along the second end edge or lower edge than in the center ofthe foam insulation layer. In other words, the foam insulation layer maybe thought of as having a top region, a bottom region, and a middleregion, and the middle region has a lower foam density than at least oneof the top region and the bottom region, and possibly both the top andbottom regions. This increased foam density can strengthen the joiningareas of the foam insulation layer.

Expanded or extruded polystyrene are particularly desirable materialsfor the foam insulation layer because they provide a solid feel; improvethe R-value; deaden noise transmitted through the panel; and allowmoisture to migrate away from the exterior wall into the externalenvironment, protecting the exterior wall behind the foam insulationlayer and reducing the risk of mold growth.

The veneer panel is optional and is not present in all embodiments, butis generally desired. The veneer panel provides environmental resistanceand durability. It is contemplated that the veneer panel is generallycontoured to conform to the contours of the foam insulating layer.Generally, siding must be thick to resist sagging and retain the desiredshape. However, the foam insulating layer allows the veneer panel to bethinner than otherwise necessary. The veneer panel only has to provideweatherability to the composite siding panel. Whereas traditional vinylveneer sidings have a minimum material thickness of 0.040 inches, theveneer panels used in this disclosure may have a thickness of from 0.020to 0.036 inches.

The veneer panel can be formed from any suitable polymeric, metallic,cementitious, or composite material. Exemplary materials include vinyl,polypropylene, fiber-cement material, polyolefins, polyvinyls,polycarbonates, polyacetals, polysulfones, polyesters, polyamides,multilayer films, polyethylene including high density polyethylene(HDPE) and low density polyethylene (LDPE), polypropylene, CPVC ABS,ethyl-vinyl acetate, various extruded ionomeric films,polyethylene-based films, wood, or combinations thereof. Other sidingmaterials suitable for the veneer panel include wood, aluminum, andsteel.

If desired, the rear face of the foam insulating layer may also havedrainage grooves formed or fabricated into it. Such grooves aredescribed in U.S. Patent Publication Nos. 2005/0081468 and 2007/0175154,the disclosures of which are hereby fully incorporated by reference.

The insulation panels are used in suitable combinations to be affixed toor attached to exterior walls of a building. They can be used on severaltypes of structures including, but not limited to, wood-frame, cementblock, structural insulated panels (SIPS), insulating concrete forms(ICFs), steel studs, etc. When installed, the resulting insulating layeris uniform and forms a complete seal. In addition, any perforations inthe wall are sealed off from outside elements by the insulation. Theattachment member also provides fewer perforations overall in theexterior wall. The foam insulating layer and veneer panels themselvesare not perforated either. Nails, screws, or staples can be used withequal ease and can be more accurately placed and more secure becausethey are applied directly to the exterior wall instead of through aflexible insulating layer.

Other benefits of the insulation panels described herein relate toproduction. The amount of insulation can be increased by simply addingmore foam, without any other cost in materials. A single foam insulationlayer can be used with multiple veneer panels to provide desiredassemblies. The veneer panel can be reduced in thickness, therebyreducing waste.
